====== How to integrate phpfreechat in a dokuwiki page ? ======

This method is used on the [[:demo|demo page]].

  - You have to install the [[http://www.dokuwiki.org/plugin:phpinc|phpinclude dokuwiki plugin]].
  - You have to create a ''phpinclude/'' directory in the root directory of your dokuwiki installation and a ''phpincludes/pfc-pub-data/'' directory (public pfc data will be stored here).
  - You have to create these two scripts :
    * ''phpinclude/pfc-front.php'' : this script will load the chat interface when the dokuwiki page is loaded.
    * ''phpinclude/pfc-backend.php'' : this script will be contacted by ''pfc-front.php'' using ajax call to communicate with the pfc server.
  - Finally, in the desired dokuwiki page you have to insert this code:<code>
<phpinc=pfc-front.php>
</code>
  - That's all.


===== pfc-front.php =====

Here is an example you should of course adapt to your needs:
<code php>
<?php

global $USERINFO;

require_once dirname(__FILE__).'/../src/trunk/src/phpfreechat.class.php';
$params = array();
$params['serverid'] = 'pfc-dokuwiki';
$params['nick'] = isset($USERINFO['name']) && !empty($USERINFO['name']) ?
                    $USERINFO['name'] :
                    (isset($_SERVER['REMOTE_USER']) ? $_SERVER['REMOTE_USER'] : '');
$params['isadmin']  = isset($USERINFO['grps']) ?
                        in_array('Administrators',$USERINFO['grps']) || in_array('Moderators',$USERINFO['grps']) :
                        false;
$params['data_public_path']   = dirname(__FILE__).'/pfc-pub-data';
$params['data_public_url']    = 'phpincludes/pfc-pub-data';
$params['server_script_path'] = dirname(__FILE__).'/pfc-backend.php';
$params['server_script_url']  = 'phpincludes/pfc-backend.php';

// store in session the parameters list for the backend script
@session_start();
$_SESSION['demo_params_list'] = $params;

$pfc = new phpFreeChat($params);
$pfc->printChat();

?>
</code>

===== pfc-backend.php =====

<code php>
<?php

// necessary to open the dokuwiki session
if(!defined('DOKU_INC')) define('DOKU_INC',realpath(dirname(__FILE__)).'/../');
require_once(DOKU_INC.'inc/init.php');

require_once dirname(__FILE__).'/../src/trunk/src/phpfreechat.class.php';
$plist = $_SESSION['demo_params_list'];
$chat = new phpFreeChat( $plist );

?>
